You both study in the same school, but hes 4 years older then you. While you were on 7 grade he was in his second year of highschool, he's always trying to piss you off.

While you were walking peacfully towards your next class you saw him walking to the opposite direction, right by your side, he quickly glanced at you and placed his foot in front of you for you to fall, when you did he burst out of laughing

Ace: "watch out, Sam"

He mocked you while laughing
